Learning Outcomes
Having completed the course, the student knows the principles of modern speed controlled motor drive and the principles of inverters and grid connected rectifiers used in distributed energy production and can apply acquired knowledge in the commissioning of a controlled electric drive application. The student understands the principal differences between various types of motor drives, such as scalar, vector and direct torque control. The student perceives the differences in various inverter controls used in distributed energy production, as well as the differences between the implementations of motor and energy production drives. The student understands the control principles for medium and low voltage synchronous machines, also when implemented with a frequency converter application. The student knows how to assemble a compatible entity out of individual components.
Student's Workload
135 hours, containing 50 h of scheduled contact studies. In addition to lectures, 4*4 h of laboratory work. Two hours reserved for the examination.

Contents
Principles of determining a transfer function for the student to be able to create a simulation model out of entities of various size. The starting point for the simulation model is speed and current control of a DC motor with a DC drive. Simulation models compiled from transfer functions prepared during lectures will be used for simulating the behavious of power electronics components and tuning the entities. Learning to read various control charts used in power electronics control applications. Principles of scalar, vector and direct torques control in squirrel cage motors. Most typical inverter-based control applications used indistributed energy production. The structure and control principles of grid rectifier used both in motors and energy production, also from the point of view of powers and the quality of energy. In synchronous machine applications, the principles of cycloconverter and high power DC link frequency converter. Principles and applications of permanent magnet and reluctance synchronous machine controls. EMC in controlled drives, beating currents and overvoltages and their prevention. In laboratory assignments, the most typical control applcations dealt with lectures will be studied by parametering and testing speed and torque controlled drives using various motors on various operation quandrants.
